Sine Wave Filter

Function of Sine wave filter
1. Sine wave filter could provide a sine-wave output voltage when driven from PWM inverters
2. By eliminating the high dv/dt, it could save you from the problem of overvoltage of electromotor.
3. It could eliminate the premature aging to electromotor caused by eddy current lost
4. It could reduce the noise made by electromotor

Feature of Sine Wave Filter
1. Our sine wave filter adopts foil winding structure. It features low DC resistance, high anti-electromagnetic performance, and large short-term overload capacity.
2. It adopts high-performance composite insulation material (above F), which enables it to maintain reliable performance in harsh working conditions.
3. It is highly-insulated and could endure high dv/dt voltage surge.
